ML who's clumsy/unlucky but it's all intentional

Like the title :D

I’m not sure if this drama fits here or not but ‘Psychopath Diary’. The ml thinks he’s a psychopath and ‘pretends’ to be clumsy/nice to everyone (when in reality, he’s actually a nice guy but he didn’t know haha).

+ Big Mouth
Awaken 

first thing I thought of was The Rise of Phoenixes — although the ML isn't really clumsy, but more intentionally pretending to be weak and useless
